Exercise and Your Brain

  When I wrote The Inner Runner, one of the things I wanted to address is how running changes us on the inside. Exercise doesn’t just affect the heart and muscles; it also affects the brain. It’s an interesting field of science called neuroplasticity—the ability of the brain to change. Running causes morphological and neurochemical adaptations […]

Do Your Lungs Limit Performance?

Many new runners complain that they can’t breathe even on short runs. Indeed, getting in enough air is foremost on their minds. It’s a marvel of physiology that enough air gets into our bodies, with our nostrils being no larger than the size of a pea. Even the space between semi-pursed lips is small considering […]

Running the Right Pace

I was asked today if I could share some advice in my blog about how to learn to run at the correct speed. Well, of course I can! Most runners train haphazardly, without any real sense of purpose, and then are often disappointed with their racing results. When you train with a purpose and understand […]

New York City Marathon Prep and VO2max

With 5 weeks to go until the New York City Marathon, I’ve started to include some interval training in my marathon preparation. Once per week, I’m going to the track to push my heart rate to it’s maximum to attend to my VO2max. Sounds like fun, doesn’t it? Given the popularity of VO2max and it’s […]
